Answer:

r = 1.7389 in

Explanation:

(A) Volume of hollow block = 540 in^3

(B) volume of block without Hollows = b×d×h

= 6 ×16 ×8

= 768 in^3

(C) volume of 3 hollows = 3 ×( pi ×r^2 h)

= 3 ×( pi ×r^2 ×8)

= 24 ×pi ×r^2

solve,

A = B - C

540 = 768- (24 ×pi ×r^2)

r^2 = (768- 540) / 24 pi

r = root(3.023943919)

r = 1.7389 in
